(54) Carrier tape for electronic components


(57) The present invention is an electronic component series, comprising a carrier tape (3) which has a plurality of storage recesses (2) cyclically arranged along the longitudinal direction, electronic components (5) to be stored in the plurality of storage recesses, a cover tape (4) established to cover the plurality of storage recesses of the carrier tape, and a pair of adhesive regions (6) which adhere to the carrier tape and to the cover tape, and extend along the longitudinal direction of the carrier tape so as to enclose the plurality of storage recesses (2) from both sides, wherein the adhesive width of the pair of adhesive regions is cyclically increased in size corresponding to the storage recesses respectively. With this electronic component series, the difference in the peel strength of the cover tape between the first adhesive regions and the second adhesive regions can be sufficiently reduced.
